        "content": "Here\u2019s a detailed summary of Demko\u2019s mattresses based on their official website and recent reviews:\n\n---\n\n## What Makes Demko Mattresses Special\n\n- **100% Organic Materials**:  \n  Their mattresses use GOLS-certified organic latex, GOTS-certified coir (coconut) fibre, and either GOTS-certified organic wool or a vegan cover. ([demkousa.com](https://demkousa.com/organic-mattresses/?utm_source=openai))  \n- **Chemical & Metal-Free Build**:  \n  No metal springs and no synthetic adhesives. A thin layer of graphite\u2013infused organic latex acts as the fire barrier instead of chemical fire-retardants. ([demkousa.com](https://demkousa.com/organic-mattresses/?utm_source=openai))  \n- **Environmental & Health Focus**:  \n  The materials are renewable, biodegradable, and grow/processed without chemicals. Latex is naturally breathable, hypoallergenic, and antimicrobial. ([demkousa.com](https://demkousa.com/organic-mattresses/?utm_source=openai))  \n\n---\n\n## Key Features of Specific Mattress Models\n\nHere are two of their flagship models and what sets them apart:\n\n| Model | Firmness | Construction & Layers | Height / Size | Weight Support (per side) |\n|-------|----------|------------------------|----------------|-----------------------------|\n| **DeLuxe D** (Medium) | 6.0/10 | 8 cm organic latex + 3 cm coir + 3 cm coir + 8 cm organic latex | ~23.5 cm / 8.7\u2033 | Up to 140 kg (22 stones) per person ([demkousa.com](https://demkousa.com/shop/mattresses/medium/deluxe-d/?utm_source=openai)) |\n| **DeLuxe C** (Firm-Medium) | ~6.5/10 | 6.5 cm latex + 5 cm coir + 6.5 cm latex | ~19.5 cm / 7.7\u2033 | Up to 130 kg (about 20.5 stones) per person ([demko.co.uk](https://demko.co.uk/shop/mattresses/medium/demko-organic-mattress-deluxe-c/?utm_source=openai)) |\n\nBoth models allow for **variable firmness**: since the layers aren't glued, you can rearrange them to adjust firmness or feel depending on your preference or sleep position. ([demkousa.com](https://demkousa.com/shop/mattresses/medium/deluxe-d/?utm_source=openai))\n\n---\n\n## Certifications, Guarantees & Additional Perks\n\n- **Certifications**:  \n  All mattresses carry **GOLS (Global Organic Latex Standard)** and **GOTS (Global Organic Textile Standard)** certifications. ([demkousa.com](https://demkousa.com/shop/mattresses/medium/deluxe-d/?utm_source=openai))  \n\n- **Trial & Warranty**:  \n  You get a 30-day sleep trial and a **10-year guarantee** with purchases. ([demkousa.com](https://demkousa.com/organic-mattresses/?utm_source=openai))  \n\n- **Fire & Safety Compliance**:  \n  They meet UK standards like **BS7177 and BS5852** for fire hazard. ([demkousa.com](https://demkousa.com/shop/mattresses/medium/deluxe-d/?utm_source=openai))  \n\n- **Mattress Cover Options**:  \n  Covers are available made with organic wool & cotton, or fully vegan covers with cotton and Tencel\u2122. Some use a probiotic protection treatment (Actipro\u2122) on the Tencel\u2122 layer to control allergens, smell, etc. ([demkousa.com](https://demkousa.com/shop/mattresses/medium/deluxe-d/?utm_source=openai))  \n\n---\n\nIf you'd like, I can pull together comparisons of Demko vs. other organic mattress brands, or show pricing & dimensions in your region.

([demkousa.com](https://demkousa.com/organic-mattresses/?utm_source=openai))  \n- Each mattress complies with **UK safety/flammability standards** BS7177 and BS5852 (low domestic hazards and medium hotel hazards). ([demkousa.com](https://demkousa.com/shop/mattresses/medium/deluxe-d/?utm_source=openai))  \n- No metal springs; thin layers of graphite-infused latex serve as the fire barrier instead of chemical fire retardants.

([demkousa.com](https://demkousa.com/organic-mattresses/?utm_source=openai))  \n- All mattresses feature a thin **graphite-infused latex layer** serving as a natural fire barrier, allowing Demko to meet fire safety standards *without synthetic flame retardants*. ([demkousa.com](https://demkousa.com/organic-mattresses/?utm_source=openai))  \n\n---\n\n## Variable Firmness & Customization\n\n- Many Demko models allow **rearranging layer order** to adjust firmness. For instance, the *DeLuxe D* can be configured in three ways to shift firmness between ~5.0\u20136.0 / 10 depending on which layer is on top. ([demkousa.com](https://demkousa.com/shop/mattresses/medium/deluxe-d/?utm_source=openai))  \n- Dual-Firmness models like **DeLuxe B** and **DeLuxe A \u2013 Junior Dual** are made to offer two different firmness levels depending on how you orient the layers. ([demkousa.com](https://demkousa.com/shop/mattresses/medium/deluxe-a/?utm_source=openai))  \n\n---\n\n## Key Takeaways\n\n- If you're after **medium comfort with plushness**, the *DeLuxe D* is the deepest mattress (\u2248 23.5 cm), highest weight tolerance (\u2248140 kg), and a midpoint firmness with flexibility.  \n- For more **firm support**, especially for heavier sleepers or those who prefer a firmer surface, the *ProLuxe B*, *ProLuxe C*, or *ExtraLuxe A* offer higher firmness ratings (7\u201310 / 10).  \n- For a **lightweight actor** (or for kids/guests), the junior and lighter models like *ProLuxe A \u2013 Junior* and *DeLuxe A \u2013 Junior Dual* are more suitable.  \n- Across all models, you get strong organic / eco credentials, excellent safety compliance (no metals, no chemical fire retardants), and design meant to allow day-to-day firmness customization.\n\n---\n\nIf you like, I can also pull together **pricing by region**, shipping times, or compare exactly what these specs look like relative to other organic latex brands."
